Abstract: 
What are the excess costs of a separate 20% target for renewable energy as a part of the EU climate policy for 2020? We answer this question using a computable general equilibrium model, WorldScan, which has been extended with a bottom-up module of the electricity sector. The model set-up makes it possible to directly use available estimates of costs and capacity potentials for renewable energy sources for calibration. In our base case simulation, the excess costs of the renewables target are 6%. As information on the supply of renewable energy is scarce and uncertain, we perform an extensive sensitivity analysis with respect to the level and steepness of the supply curves for wind energy and biomass. In the range we explore, the excess costs vary from zero (when the target is not binding) to 23% (when the cost progression and the initial cost disadvantage for renewables are doubled).
